Please help me ..im begging you​
Deffense [45]

Explanation:

let's assume that:

v1= 600ml=0,6l

T1=27°C= 300K

p1=700mmHG=93326Pa

T2=-20°C=253K

p2=500mmHg=66661

V2=?

p1V1/T1=p2V2/T2 => V2=p1V1T2/p2

V2= 93326*0,6*253/66661

V2=212,52l

A marathon runner runs at a steady 15 km/hr. When the runner is 7.5 km from the finish, a bird begins flying from the runner to
Whitepunk [10]

Answer:

The value is D =  15 \  km

Explanation:

From the question we are told that

   The  speed of the marathon runner is  v  =  15 \  km /hr

   The distance from the distance from the finish is  d =  7.5 \  km

   The  speed of the bird is  v_b  =  30 \ km / hr

  Generally the time taken for the runner to reach the finish is mathematically represented as

       t =  \frac{d}{v}

       t =  \frac{7.5}{15}

        t =  \frac{1}{2}

So the distance covered by the bird is  

      D =  v_b  *  t

      D =  30  *  \frac{1}{2}

         D =  15 \  km
